Kress KR172 Mission RTKn · Mammotion Yuka 2000

Network positioning replaces wire: no perimeter to lay and no antenna, beacon or base station to mount, but the property has to be inside Kress’s RTKn coverage. Inertial navigation and odometry bridge shaded stretches, not a missing footprint.

Wire-free setup comes with a second piece of hardware to site and keep connected: the RTK station and its Wi-Fi or 4G correction link are what replace the buried perimeter.

The sweeping deck makes one machine do two jobs, and cuts the rated gradient from 28 degrees to about 10 while it is fitted.

Properties outside Kress RTKn network coverage

Positioning comes from Kress's own correction network, so the property has to sit inside its footprint. Shade is not the disqualifier: under weak satellite signal the mower switches to inertial navigation and odometry to hold its routing until a clear connection returns. A property with no network coverage at all is the case that rules the machine out.

Lawns that regularly hold small objects

The US KR172 is listed without OAS, the obstacle avoidance system Kress names in the KR173 and above. Toys, hoses and pet waste have to be picked up before a run. Some EU KR172E.A listings bundle OAS, so confirm the variant before assuming it is fitted.

Slopes above 40% gradient or soft, boggy ground

Kress rates the KR172 to a 40 percent maximum slope. Past that, and on poorly drained soil, traction rather than positioning accuracy is the limit, and centimeter-level accuracy does not compensate for a wheel that is not gripping.

Lawns above the rated area

Mammotion rates the YUKA 2000 at 2,000 m2, about 0.49 acre, reaching roughly 0.7 acre under good reception, at a mowing rate of 350 m2 per hour.

Sweeping on sloped ground

The sweeping deck drops the rated gradient to 18 percent, about 10 degrees, from 28 degrees without it. A bank that the mower handles bare is outside the rating once the sweeper is on.

Ground steeper than the machine rating

Mammotion rates the YUKA 2000 at 28 degrees, published also as a 45 percent gradient, with no sweeper fitted. Steeper banks are outside the envelope. With the sweeping deck fitted the rating falls to 18 percent, about 10 degrees.

Properties where the RTK station cannot be sited

The station needs a mounting position and a correction link over home Wi-Fi or 4G. Without somewhere to put it, the positioning the machine depends on is not available.

Owners who want no cloud account

Mapping, zone editing and scheduling run through the Mammotion app against an account, and the RTK correction link is a network service.
